Cords, cables, and hoses are either stiff and difficult to stow in a small place or flexible and easy to tangle. This means cord management is a ripe target for innovation. Cords need to be coiled so they can easily be removed from stowage without being tangled. Some sort of container for the cord will help keep it protected as well as help keep it from tangling with other cords. One container convenient for RV’s is the cloth conference bag. You can find these at thrift stores for a minimal expense. Other options are fancier, look prettier, or just more convenient, maybe.
Caveat: If you are running power through a cord, keeping it coiled, especially in a confined space, may not be a good idea. Power cords dissipate heat and need appropriate air flow.
Cool Tools takes note of the Cordpro® as a way to manage cords, cables, and hoses. Following the link to the Cordpro website finds a tip that might be useful with or without the device. “Cords operate more easily when coated with a thin layer of F21 Turtle Wax Super Protectant before storing in your Cordpro®. Additionally, this provides ultraviolet protection, which will increase the life of your cords and hoses.”
The key to this cord management tool is that it uses a divided flexible plastic container to hold rolled up cord. Half is wound around one side and half around the other. The flexible lip holds the cord but allows it to be pulled out or rewound. The two compartments allow pulling cord out from each end.
Cableyoyo is an example of this technique for USB cables. That helps keep your laptop workstation and accessories neat.
If YoYos aren’t your style, try turtles. The container store calls them Cable Turtles.
Ehow has a video on using a bucket for a similar purpose. That doesn’t have the ‘pull from either end’ convenience but may be something to consider.

If you’ve got an RV with 50 amp service, you might consider looking into how the Navy trains sailors to manage hawsers for ideas on dealing with your power cord. Those cords are heavy and seem to have a mind of their own.
